Product Description

The 6ES5261-5AA21 module is a robust SIMATIC S5 PLC component designed for industrial automation systems. This S5-261 module integrates 16 digital inputs and 12 digital outputs, supporting direct expansion with up to 4 additional I/O modules via its modular backplane. It operates on 24V DC (±15% tolerance) within a temperature range of 0°C to 60°C, ensuring reliability in harsh environments like manufacturing and process industries. Communication interfaces include RS-485 via the integrated AS-511 port for programming and data exchange. Known for high durability and backward compatibility with S5 ecosystems, its drawbacks include limited support for modern protocols. The module lacks an internal battery or display, focusing instead on stable performance for machine control, logistics, and energy management applications. Its compact design prioritizes functional density over extended diagnostic features.
